I have a form class SomeForm extends MyObjectForm
MyObjectForm is a sfFormObject form of the object MyObject.
I want to add a widget named extra to SomeForm but that's not a field of the object MyObject, and when i try to save the form i get an error:
500 | Internal Server Error | Doctrine_Record_UnknownPropertyException
Unknown record property / related component "extra" on "MyObject"
Try unsetting it in SomeForm::processValues()
public function processValues($values) {
unset($values['extra']);
return $values;
}

I'm just getting to grips with ViewComponents in my Razor pages application.
I have a ViewComponents folder within my project that contains my ViewComponent .cs code:
public class RemoveFromCartViewComponent : ViewComponent
{
public IViewComponentResult Invoke()
{
var result = "123";
return View(result);
}
}
I then have another folder within Pages/Shared/Components called RemoveFromCart. Within this folder I have my default.cshtml
#model string
<h2>
#Model
</h2>
Simply putting the string within a h2 tag.
In my projects Layout.cshtml file I am invoking this ViewComponent:
<div>
#await Component.InvokeAsync("RemoveFromCart")
</div>
When I start my project, the error I get is:
*InvalidOperationException: The view 'Components/RemoveFromCart/123' was not found. The following locations were searched:
/Pages/Components/RemoveFromCart/123.cshtml
/Pages/Shared/Components/RemoveFromCart/123.cshtml
/Views/Shared/Components/RemoveFromCart/123.cshtml*
This is indication my view should be called 123.cshtml which doesnt seem right. What am I doing wrong here? I should simply expect to see the text 123 appear
Thanks
By returning View("123"), you are using this overload:
public ViewViewComponentResult View (string viewName)
Returns a result which will render the partial view with name viewName.
So you are passing the view name, instead of a string value as the view’s model.
You can change that by explicitly calling the View<TModel>(TModel) overload instead:
public IViewComponentResult Invoke()
{
var result = "123";
return View<string>(result);
}
In the long run, I would suggest you to create a model class instead so that you can pass an object instead of just a string. This will avoid having this particular problem and you are also able to easily expand the model contents later on.
i have two jsf pages (home.jsf and employees.jsf) ,
home page has a button that navigates to employees page,
while navigating i store value in session scope
at (Managed bean)
public void putSessionAL(ActionEvent actionEvent) {
FacesContext.getCurrentInstance().getExternalContext().getSessionMap().put("key","value");
}
public String navigate() {
return "employees";
}
i want to change Label at employees viewObject from UIHints tab depending on value stored at session using the following groovy expression
adf.context.sessionScope.key
and changed trustMode to trusted but it fires the following exception
oracle.jbo.script.ExprScriptException: JBO-29114 ADFContext is not setup to process messages for this exception. Use the exception stack trace and error code to investigate the root cause of this exception. Root cause error code is JBO-25188.

One way to do it at the VO UIHint attribute label level will be programmaticaly by doing as follow :
In your VO go to the java tab and add the RowImpl java class
In the VORowImpl Add the following function
public String getMySessionLabel() {
return (String)FacesContext.getCurrentInstance().getExternalContext().getSessionMap().get("key");
}
In the Label add the following EL expression :
adf.object.getMySessionLabel()
This technique allow you more control than pure EL, if you want to do more than getting from session for example. In your case pure EL, as you did, should work as well. (Would need to check what is wrong with yours, maybe just missing the
#{adf.context.sessionScope.key}
If you attempt to get your label from a method in viewRowImpl. So this will be executed at least once for each row. I think this solution isn't fit for your case.
anyway ADF as a framework added strong policy and validations in EL in general and especially in version 12.2.x.
The solution for you case as following:
Create new class in model layer which extends oracle.jbo.script.ExprSecurityPolicy class
Override checkProperty method.
#Override
public boolean checkProperty(Object object, String string, Boolean b) {
if (object.getClass().getName().equals("oracle.adf.share.http.ServletADFContext") && string.equals("sessionScope")) {
return true;
}
return super.checkProperty(object, string, b);
}
Open adf-config.xml source and in startup tag set your class ExprSecurityPolicy property.
like:
<startup ExprSecurityPolicy="model.CustomExprSecurityPolicy">
So, I'm working with ServiceStack, and know my way around a bit with it. I've used AutoQuery and find it indispensable when calling for straight 'GET' messages. I'm having an issue though, and I have been looking at this for a couple of hours. I hope it's just something I'm overlooking.
I have a simple class set up for my AutoQuery message:
public class QueryCamera : QueryDb<db_camera>
{
}
I have an OrmLite connection that is used to retrieve db_camera entires from the database. this all works just fine. I don't want to return a model from the database though as a result, I'd like to return a DTO, which I have defined as another class. So, using the version of QueryDb, my request message is now this:
public class QueryCamera : QueryDb<db_camera, Camera>
{
}
Where the Camera class is my DTO. The call still executes, but I get no results. I have a mapper extension method ToDto() set up on the db_camera class to return a Camera instance.
Maybe I'm just used to ServiceStack making things so easy... but how do I get the AutoQuery request above to perform the mapping for my request? Is the data retrieval now a manual operation for me since I'm specifying the conversion I want? Where's the value in this type being offered then? Is it now my responsibility to query the database, then call .ToDto() on my data model records to return DTO objects?
EDIT: something else I just observed... I'm still getting the row count from the returned dataset in AutoQueryViewer, but the field names are of the data model class db_camera and not Camera.
The QueryDb<From, Into> isn't able to use your Custom DTO extension method, it's used to select a curated set of columns from the executed AutoQuery which can also be used to reference columns on joined tables.
If you want to have different names on the DTO than on your Data Model, you can use an [Alias] attribute to map back to your DB column name which will let you name your DTO Property anything you like. On the other side you can change what property the DTO property is serialized as, e.g:
[DataContract]
public class Camera
{
[DataMember(Name = "Id")] // serialized as `Id`
public camera_id { get; set; } // populated with db_camera.camera_id
[DataMember]
[Alias("model")] // populated with db_camera.model
public CameraModel { get; set; } // serialized as `CameraModel`
}
In jcouchdb I used to extend BaseDocument and then, in a transparent manner, mix Annotations and not declared fields.
Example:
import org.jcouchdb.document.BaseDocument;
public class SiteDocument extends BaseDocument {
private String site;
#org.svenson.JSONProperty(value = "site", ignoreIfNull = true)
public String getSite() {
return site;
}
public void setSite(String name) {
site = name;
}
}
and then use it:
// Create a SiteDocument
SiteDocument site2 = new SiteDocument();
site2.setProperty("site", "http://www.starckoverflow.com/index.html");
// Set value using setSite
site2.setSite("www.stackoverflow.com");
// and using setProperty
site2.setProperty("description", "Questions & Answers");
db.createOrUpdateDocument(site2);
Where I use both a document field (site) that is defined via annotation and a property field (description) not defined, both get serialized when I save document.
This is convenient for me since I can work with semi-structured documents.
When I try to do the same with Ektorp I have documents using annotations and Documents using HashMap BUT I couldn't find an easy way of getting the mix of both (I've tried using my own serializers but this seems to much work for something that I get for free in jcouchdb). Also tried to annotate a HashMap field but then is serialized as an object and I get the fields automatically saved BUT inside an object with the name of the HashMap field.
Is it possible to do (easily/for free) using Ektorp?
It is definitely possible. You have two options:
Base your class on org.ektorp.support.OpenCouchDbDocument
Annotate the you class with #JsonAnySetter and #JsonAnyGetter. Red more here: http://wiki.fasterxml.com/JacksonFeatureAnyGetter
I have some problems with getting the RefreshRequested event to work in one of my ViewControllers that implements the DialogViewController:
public CustomViewController () : base (null, true) {
RefreshRequested += delegate {
...
ReloadComplete ();
};
}
I am calling the CustomViewController from another ViewController like this:
var dvc = new CustomViewController();
this.ActivateController(dvc);
The error message I get is "Toplevel exception: System.ArgumentException: You should set the handler before the controller is shown"
Any pointers of what I am doing from here? Thanks
It looks like you do not have a RootElement specified, i.e. it's set to null by your own constructor, so you get warned that the internal state is not ready to set the event.
You should create an empty RootElement with your constructor and, later, add stuff to it (using the property). That should allow you to set the event in your own constructor. E.g.
public CustomViewController () : base (new RootElement (String.Empty), true)
Any pointers of what I am doing from here?
In doubt you can always see the entire source code MonoTouch.Dialog in it's github repository.
From my testing, the only place that you can set the event handler is in the constructor of the ViewController, as that's the only place where you can rely on the fact that the TableView property is null. I've tried the suggestion above of setting the RootElement in the constructor, but then always seem to have a TableView object before I can set the event handler. The problem with setting the event handler in the constructor though is that I don't have any way of resetting the event handler after cleaning it up.
